DiabloSport inTune i3 Tuner


I got the programmer to adjust the cooling fan temp setting and turn off the MDS. It has done just that, my engine temp is running just right and the MDS is off. MDS is the best example of over engineering I can think of. View more reviews...

DiabloSport Trinity T2 EX Tuner

Larry Adams, Old dog new tricks

I bought a 2013 CTS coup with a V-6 engine about 320hp new for my wife, it runs OK but not like the CTS-V's. So I wanted to see what would happen with a turner and bought this Diablo, I really like the gages it's like the "heads up" my GMC Denali has. I the first tune I loaded (the modified stock) did not impress me, so I loaded the 91 octane program. I AM IMPRESSED! The car is faster in automatic but, in automatic stick shift you really feel it. Buy one and try it. View more reviews...

DiabloSport Predator P2 Tuner

great product

I did have an edge programmer before that worked but started having issues with it. Now that I switched I am very happy. I mostly do what I can for economy and this product has helped. I get almost 23 mph on highway that's more than I get with the edge. I did try the other modes and they did hurt mileage but it did open up the truck. I'm very satisfied with this tuner, might get the trinity some time in the future. View more reviews...
